Wound dressing

Abstract

The wound dressing combines an integrated mechanical aspirator for drawing exudate and fluids from the wound site and an internal absorbent pad for collecting exudate and fluids within the wound dressing. The collection pad has multi-layers including a layer of hyper-absorbent material, which acts as the fluid collection medium. The aspirator is a type of simple bulb syringe, which is integrated into top of the wound dressing in fluid communication with the collection pad. The aspirator has a hollow bulb head and a one-way purge vent. The vent allows air to be purged from the bulb head when manually compressed. Once compressed, the structural and material resilience of the bulb head causes its walls to expand back to their original shape thereby creating a vacuum (negative) pressure within the bulb head that assists in drawing exudate and fluids from the wound site into the collection pad.

Description

TECHNICAL FIELD[0001]This invention relates to a wound dressing, and in particular a wound dressing including an integrated aspirator and exudate collection pad.BACKGROUND ART[0002]Negative pressure wound therapy has proven effective in promoting the healing of wounds. Negative pressure wound therapy involves connecting an external vacuum source to a hermetically sealed wound dressing to draw and collect exudate from the wound. While readily available in clinical settings, the apparatus for facilitating negative pressure wound therapy in the field are seldom available or convenient to use.DISCLOSURE OF THE INVENTION[0003]The wound dressing of this invention combines an integrated simple mechanical aspirator for drawing exudate and other fluids from the wound site and an internal absorbent pad for collecting the exudate and other fluids within the wound dressing itself.

AI Technical Summary

Benefits of technology

[0003]The wound dressing of this invention combines an integrated simple mechanical aspirator for drawing exudate and other fluids from the wound site and an internal absorbent pad for collecting the exudate and other fluids within the wound dressing itself. The collection pad has multi-layers including a layer of hyper-absorbent material, which acts as the fluid collection medium. In one embodiment, the aspirator is a type of simple bulb syringe, which is integrated into the top of the wound dressing in fluid communication with the collection pad. The aspirator is formed, molded or otherwise made having a hollow bulb head and a one-way purge vent. The vent allows air to be purged from the bulb head when manually compressed. Once compressed, the structural and material resilience of the bulb head causes its walls to expand back to their original shape thereby creating a vacuum (negative) pressure within the bulb head that assists in drawing exudate and fluids from the wound site into the collection pad.

Problems solved by technology

While readily available in clinical settings, the apparatus for facilitating negative pressure wound therapy in the field are seldom available or convenient to use.
